fix(runtime,hands): 4项根因修复 — URL编码/Browser桩/定时解析/LLM超时

1. researcher.rs: url_encode() chars→bytes，修复中文搜索URL编码
   (U+533B→%533B 改为 UTF-8 %E5%8C%BB)
2. browser.rs: WebDriver不可用时返回明确错误而非静默成功，
   防止LLM误以为操作已完成
3. nl_schedule.rs: 新增相对延迟解析(秒后/分钟后/小时后)，
   避免fallback到LLM幻觉cron
4. 4个LLM driver: 移除http1_only()防reqwest解码错误，
   超时120s→300s适配工具调用链，Anthropic裸Client::new()补全配置
